Remarks

In a recently published paper, Löser (2011) re-instated the genus on the basis of the presence of conical monticules in Helladastraea and the development of polygonal monticules in Aspidiscus, and noted that: "The genus was originally introduced as a subgenus of Aspidiscus. Today it is generally considered a junior synonym of this genus (e. g. GILL and LAFUSTE 1987). Helladastraea differs from Aspidiscus in having conical monticules whereas Aspidiscus has polygonal monticules, in some species mixed with conical monticules." Since this statement proves that Helladastraea represents a variation of Aspidiscus, they are considered synonymous.
